The equation to determine the amount of left over kitchen shelving paper is; L = 53/4 - (21/2)x.
For the given question;
Martha purchased 6 kitchen shelves with shelving paper.
The length of 6 shelves is 1 3/4 feet = 7/4 feet.
Thus, the total length of the 6 shelving papers is 6× 7/4 = 21/2 feet
The corrected width of the shelving paper is 13 1/4 = 53/4 feet.
The equation to defined the left over papers 'L'.
Let number of shelves be 'x'.
L = 53/4 - (21/2)x.
Thus, the equation to determine the amount of left over kitchen shelving paper is; L = 53/4 - (21/2)x.

The correct question is-
Martha is covering kitchen shelves with shelving paper. She has 6 shelves that are each 1 3/4 feet long. She buys 13 1/4 feet of shelving paper of the correct width. Which equation can be used to determine how much paper she will have left over?
The correct expression is 13 1/4 − 6(1 3/4) = S. You take the total amount you have and subtract how much you need, 6 shelves each 1 3/4 feet long.
i think the answer is A.
Choose all answers that are correct.
A.
Translate into an equation.
2,345 – 1,123 + 1,020 = p
B.
Work backward.
Add 1,020 to the population of Rosetown (1,123). Subtract this from the population of Grayville (2,345).
C.
Use logical reasoning.
Start with the population you already know (Grayville = 2,345). Subtract Rosetown's 1,123 fewer people than Grayville. Add 1,020 to this amount because Newtown has 1,020 more people than Rosetown.
D.
Draw a diagram.
Draw 3 large circles. Write 2,345 in the first circle and write 1,123 in the second circle. Add the 2 amounts and subtract 1,020 from the sum. Write this amount in the third circle.
B. y = 3x - 2
C. y = - 3x + 2
D. y = - 1/3x + 2
